A Complete Guide to the Math in the ATI TEAS 7 Test

The ATI TEAS 7 (Test of Essential Academic Skills), developed by the Assessment Technologies Institute (ATI), is a standardized test used across the United States to determine whether candidates are academically prepared to enter nursing and allied health programs. This exam evaluates four major areas of academic performance: Reading, Mathematics, Science, and English and Language Usage.

Among these, the Mathematics section is especially critical, as it measures skills essential for real-world healthcare environments where dosage calculations, data interpretation, and accurate numerical reasoning are frequently required. To perform well, students need to understand not just the content, but also the structure and intent of the test.

General Structure of the TEAS 7 Test

Before focusing solely on the Mathematics portion, it’s important to understand how the test is organized. The TEAS 7 comprises 170 multiple-choice questions divided across four subject areas:

• Reading: 53 questions (64 minutes)
  
  
• Mathematics: 36 questions (54 minutes)
  
  
• Science: 53 questions (63 minutes)
  
  
• English and Language Usage: 28 questions (28 minutes)

This totals 209 minutes (just under 3.5 hours). Out of the 170 questions, only 150 are scored; the remaining 20 are unscored pretest questions used by ATI for research purposes.

The Mathematics section represents approximately 21% of the entire test, making it a significant component, especially if you’re applying to competitive health science programs.

Format of the TEAS 7 Math Section

The Mathematics portion of the TEAS 7 is divided into two major categories:

1. Numbers and Algebra
   
   
2. Measurement and Data

The questions are multiple-choice and presented in a computer-based format. Students are allowed to use a four-function calculator, which will either be embedded in the digital version of the test or provided by the testing center if taking a paper version.

You’ll face 36 math questions and have 54 minutes to answer them, meaning you have an average of 1.5 minutes per question. Efficient time management and familiarity with question types are critical to maximizing your score.

What the Math Section Is Designed to Measure

The TEAS Math section is not about solving abstract theoretical problems. Instead, it focuses on real-life mathematical reasoning skills that nurses and healthcare workers use daily. You’ll be expected to perform the following tasks:

• Learn the common formulas and avoid wasting time trying to derive them during the test.

Importance of Word Problems

A notable feature of the TEAS 7 Math section is its frequent use of word problems. These problems assess your ability to translate real-life situations into mathematical expressions and solve them correctly.

Example:
A nurse administers a medication at a dosage of 2 mg per kg of body weight. If a patient weighs 70 kg, how many mg of medication should be given?

To answer this, you multiply:
2 mg/kg × 70 kg = 140 mg

This type of question simulates real tasks nurses perform, reinforcing the test’s practical relevance.

Tools You’ll Use: Calculator and Scratch Paper

The four-function calculator allowed during the test is essential for operations like long division or multi-step decimal problems. However, do not rely on it entirely. Practicing mental math and estimation will save time.

Working with Fractions and Decimals

Adding, Subtracting, Multiplying, and Dividing Fractions

Fractions are tested frequently on the TEAS 7. Whether in pure computation or embedded in word problems, you must be confident with operations on both proper and mixed fractions.

Key Concepts:

• Common denominators are required for addition and subtraction.
  
  
• Multiplication involves multiplying numerators and denominators directly.
  
  
• Division requires multiplying by the reciprocal.

Example:
What is the result of 34+25\frac{3}{4} + \frac{2}{5}43​+52​?

To add:

• Find the least common denominator (20)
  
  
• Convert: 34=1520,25=820\frac{3}{4} = \frac{15}{20}, \frac{2}{5} = \frac{8}{20}43​=2015​,52​=208​
  
  
• Add: 1520+820=2320=1320\frac{15}{20} + \frac{8}{20} = \frac{23}{20} = 1\frac{3}{20}2015​+208​=2023​=1203​

Decimals and Their Operations

You also need to understand how to:

• Add and subtract decimals
  
  
• Multiply and divide decimals (especially involving money or measurements)
  
  
• Compare and round decimals

Tip: Line up the decimal points for addition and subtraction; remove them temporarily for multiplication.

Example:
Multiply 1.2 × 0.3 = 0.36

Ratios and Proportions

Simplifying Ratios

Ratios compare two quantities and are tested both in abstract questions and in context, such as medication dosages or recipe calculations.

Example:
Simplify the ratio 10:25.

Divide both numbers by their greatest common factor (5):
10 ÷ 5 = 2, 25 ÷ 5 = 5 → Simplified ratio = 2:5

Solving Proportions

A proportion is an equation stating that two ratios are equal. Cross-multiplication is the standard method for solving proportions.

Example:
If 23=x9\frac{2}{3} = \frac{x}{9}32​=9x​, then cross-multiply:
2 × 9 = 3 × x → 18 = 3x → x = 6

TEAS Tip: Many dosage problems are phrased as proportions:
If a nurse gives 500 mg for a 50 kg patient, how much for a 70 kg patient?
Set up proportion: 50050=x70\frac{500}{50} = \frac{x}{70}50500​=70x​

Percentages in Healthcare Contexts

Percent problems are especially relevant in healthcare, involving scenarios like sales tax, tips, discounts, or medication concentrations.

Converting Between Fractions, Decimals, and Percents

• To convert a decimal to percent: multiply by 100
  
  
• To convert percent to decimal: divide by 100
  
  
• To convert a fraction to percent: convert to decimal, then multiply by 100

 Example:
35=0.6=60%\frac{3}{5} = 0.6 = 60\%53​=0.6=60%

Percent Increase and Decrease

These often appear in dosage and billing questions.

Formula:

• Increase: New=Original+(Original×Percent)\text{New} = \text{Original} + (\text{Original} \times \text{Percent})New=Original+(Original×Percent)
  
  
• Decrease: New=Original−(Original×Percent)\text{New} = \text{Original} – (\text{Original} \times \text{Percent})New=Original−(Original×Percent)

Example:
The medication price increased by 20% from $30.
Increase: 30×0.2=630 \times 0.2 = 630×0.2=6 → New price = $36

Solving Percent Word Problems

Use the formula:
Part = Percent × Whole

 Example:
What is 25% of 64?
0.25×64=160.25 \times 64 = 160.25×64=16

Another form:
Percent = (Part ÷ Whole) × 100

Algebraic Expressions

You’ll be asked to simplify expressions, apply properties, and evaluate variables.

Simplifying and Evaluating Expressions

Apply the order of operations (PEMDAS) and combine like terms.

Example:
Simplify: 3x+5x−2=8x−23x + 5x – 2 = 8x – 23x+5x−2=8x−2

Distributive Property

The distributive property is used to eliminate parentheses:
a(b + c) = ab + ac

Example:
Simplify: 4(x−3)=4x−124(x – 3) = 4x – 124(x−3)=4x−12

Substituting Values into Expressions

You may be asked to substitute values into algebraic expressions.

 Example:
Evaluate 2x+3y2x + 3y2x+3y for x=2,y=4x = 2, y = 4x=2,y=4
2(2)+3(4)=4+12=162(2) + 3(4) = 4 + 12 = 162(2)+3(4)=4+12=16

Linear Equations and Inequalities

One-Step and Multi-Step Equations

TEAS math will test basic algebraic problem solving.

 Example:
Solve 5x−7=185x – 7 = 185x−7=18
Add 7: 5x=255x = 255x=25 → Divide: x=5x = 5x=5

One-Step and Multi-Step Inequalities

Solve inequalities using the same rules as equations, with one exception:
Flip the inequality sign if multiplying or dividing by a negative.

Example:
Solve −2x<6-2x < 6−2x<6 → Divide by -2 → x>−3x > -3x>−3

Graphing Inequalities

You won’t be asked to draw graphs but may need to interpret inequality conditions.

Example:
“More than 5” → x>5x > 5x>5

Systems of Equations

TEAS 7 may include simple systems of equations. You’ll need to solve for two variables.

Solving by Substitution or Elimination

System:

1. x+y=10x + y = 10x+y=10
   
   
2. x−y=2x – y = 2x−y=2

Add both equations:
(x+y)+(x−y)=10+2→2x=12→x=6(x + y) + (x – y) = 10 + 2 → 2x = 12 → x = 6(x+y)+(x−y)=10+2→2x=12→x=6

Substitute into first:
6+y=10→y=46 + y = 10 → y = 46+y=10→y=4

Graphing Linear Equations

You don’t have to draw graphs on the test, but you need to recognize slopes and intercepts.

Slope-Intercept Form:
y=mx+by = mx + by=mx+b

• m = slope
  
  
• b = y-intercept

 Example:
If y=2x+3y = 2x + 3y=2x+3, slope = 2, intercept = 3

Finding Slope Between Two Points:
Use formula:
m=y2−y1x2−x1m = \frac{y_2 – y_1}{x_2 – x_1}m=x2​−x1​y2​−y1​​

Exponents and Roots

Properties of Exponents

• am×an=am+na^m × a^n = a^{m+n}am×an=am+n
  
  
• am÷an=am−na^m ÷ a^n = a^{m-n}am÷an=am−n
  
  
• (am)n=amn(a^m)^n = a^{mn}(am)n=amn
  
  
• a0=1a^0 = 1a0=1

Example:
32×34=363^2 × 3^4 = 3^632×34=36

Negative and Zero Exponents

• a−n=1ana^{-n} = \frac{1}{a^n}a−n=an1​
  
  
• a0=1a^0 = 1a0=1

Radicals and Square Roots

Understand basic root operations:

• 25=5\sqrt{25} = 525​=5
  
  
• 49=7\sqrt{49} = 749​=7

Simplifying expressions like 50=25×2=52\sqrt{50} = \sqrt{25×2} = 5\sqrt{2}50​=25×2​=52​

Word Problems and Translation

Word problems test your ability to interpret real-life scenarios using algebra.

Example:
A nurse has a 500 mL IV bag to deliver at a rate of 50 mL/hour. How long will it last?
500÷50=10500 ÷ 50 = 10500÷50=10 hours

Tips:

• Translate keywords:
  
  
  • “Increased by” → addition
    
    
  • “Difference” → subtraction
    
    
  • “Product” → multiplication
    
    
  • “Quotient” → division

Common Mistakes to Avoid

• Forgetting to reverse inequality signs when dividing by a negative
  
  
• Ignoring parentheses in order of operations
  
  
• Confusing fraction operations
  
  
• Incorrectly converting between percentages and decimals
  
  
• Misreading word problems

Tip: Always re-read the problem and check if your answer makes logical sense.

Study Strategies for Numbers and Algebra

• Use flashcards for percent formulas and exponent rules
  
  
• Create your own ratio and percent word problems to solve
  
  
• Practice translating phrases into algebraic expressions

The ATI TEAS 7 Math section contains 36 multiple-choice questions, and about 16–18 of those come from the Measurement and Data domain. This section is not just about measuring objects or reading rulers—it covers essential skills that nursing professionals use daily, such as interpreting graphs, converting between units, analyzing statistics, and solving geometry problems.

Let’s dive into the key topic areas tested in this domain, including:

• Unit conversions
  
  
• Perimeter, area, volume
  
  
• Geometry principles
  
  
• Interpreting charts and graphs
  
  
• Understanding statistics
  
  
• Probability, combinations, and permutations
  
  

These skills ensure you’re able to handle quantitative reasoning tasks in real-world healthcare settings.

Measurement: Units, Conversions, and Applications

Understanding Units of Measurement

The ATI TEAS 7 includes questions based on both the metric system and the imperial (U.S. customary) system. You should be familiar with:

• Length: inches, feet, centimeters, meters
  
  
• Volume: milliliters, liters, ounces, cups
  
  
• Weight: grams, kilograms, pounds, ounces
  
  
• Temperature: Celsius and Fahrenheit

Converting Between Units

Metric conversions rely on powers of 10. Use the base units and prefixes:

• Kilo- (1000)
  
  
• Hecto- (100)
  
  
• Deca- (10)
  
  
• Unit (meter, liter, gram)
  
  
• Deci- (0.1)
  
  
• Centi- (0.01)
  
  
• Milli- (0.001)

 Example 1:
Convert 5,000 milliliters to liters.
1,000 mL = 1 L → 50001000=5\frac{5000}{1000} = 510005000​=5 L

Imperial conversions require memorization of some common relationships:

• 12 inches = 1 foot
  
  
• 3 feet = 1 yard
  
  
• 16 ounces = 1 pound
  
  
• 8 ounces = 1 cup
  
  
• 2 cups = 1 pint
  
  
• 2 pints = 1 quart
  
  
• 4 quarts = 1 gallon

Example 2:
Convert 3 feet to inches.
3×12=363 × 12 = 363×12=36 inches

TEAS Tip: Use the conversion factor method:
Multiply the original measurement by the appropriate conversion ratio.

Geometry: Shapes, Perimeter, Area, and Volume

Perimeter and Area

You’ll be expected to solve problems involving 2D shapes such as rectangles, triangles, circles, and trapezoids.

Formulas to Remember:

• Rectangle
  Perimeter = 2l+2w2l + 2w2l+2w
  Area = l×wl × wl×w
  
  
• Triangle
  Perimeter = sum of sides
  Area = 12×base×height\frac{1}{2} × base × height21​×base×height
  
  
• Circle
  Circumference = 2πr2πr2πr or πdπdπd
  Area = πr2πr^2πr2
  
  
• Trapezoid
  Area = 12×(base1+base2)×height\frac{1}{2} × (base_1 + base_2) × height21​×(base1​+base2​)×height
  
  

Example Problem:
Find the area of a triangle with a base of 10 cm and a height of 6 cm.
Area = 12×10×6=30\frac{1}{2} × 10 × 6 = 3021​×10×6=30 cm²

Volume of 3D Shapes

Formulas to Know:

• Cube
  Volume = s3s^3s3
  
  
• Rectangular prism
  Volume = l×w×hl × w × hl×w×h
  
  
• Cylinder
  Volume = πr2hπr^2hπr2h

 Example:
A cylinder has a radius of 3 cm and height of 10 cm.
Volume = π×32×10=π×9×10=90ππ × 3^2 × 10 = π × 9 × 10 = 90ππ×32×10=π×9×10=90π ≈ 282.74 cm³

Surface Area (Conceptual Only)

While the TEAS may not require complex surface area problems, you should know what it represents: the total area covering the outside of a 3D shape.

Pythagorean Theorem

Used in right triangles, this is essential for solving unknown side lengths.

Formula:
a2+b2=c2a^2 + b^2 = c^2a2+b2=c2
Where ccc is the hypotenuse (longest side)

 Example:
A triangle has legs 6 cm and 8 cm. Find the hypotenuse.
62+82=c26^2 + 8^2 = c^262+82=c2 → 36 + 64 = 100 → c=10c = 10c=10

Data Interpretation: Graphs and Charts

Reading Graphs Accurately

You’ll need to interpret data from:

• Bar graphs
  
  
• Line graphs
  
  
• Pie charts
  
  
• Tables
  
  
• Histograms

 Bar and line graphs show changes over time or comparisons between groups.
Pie charts show parts of a whole.
Tables present organized data in rows and columns.
Histograms are similar to bar graphs but display frequency distributions for continuous data.

TEAS Tip: Always:

• Check labels and units
  
  
• Read the title
  
  
• Identify scales and increments

Example Problem:

A pie chart shows 25% of patients had Type A blood. If there are 400 patients, how many have Type A?

25% of 400 = 0.25×400=1000.25 × 400 = 1000.25×400=100 patients

Statistics: Central Tendency and Spread

Mean, Median, Mode, and Range

Understanding these values is essential in analyzing data trends and drawing conclusions.

• Mean (average):
  Add all values and divide by how many there are.
  
  
• Median:
  The middle value when numbers are in order.
  
  
• Mode:
  The most frequent value.
  
  
• Range:
  Difference between highest and lowest values.

Example Set: 3, 5, 7, 7, 9
Mean: 3+5+7+7+95=31/5=6.2\frac{3+5+7+7+9}{5} = 31/5 = 6.253+5+7+7+9​=31/5=6.2
Median: 7
Mode: 7
Range: 9−3=69 – 3 = 69−3=6

Using Statistics in Healthcare

Healthcare professionals use statistics to:

• Analyze patient vitals
  
  
• Track medication efficacy
  
  
• Identify patterns in lab results

Probability: Predicting Outcomes

Basic Probability

Formula:
Probability=Number of favorable outcomesTotal possible outcomes\text{Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total possible outcomes}}Probability=Total possible outcomesNumber of favorable outcomes​

Example:
A jar has 3 red, 4 green, and 5 blue marbles.
Probability of picking a green marble:
43+4+5=412=13\frac{4}{3+4+5} = \frac{4}{12} = \frac{1}{3}3+4+54​=124​=31​

Complementary Events

The probability of something not happening:
P(not A)=1−P(A)P(\text{not A}) = 1 – P(A)P(not A)=1−P(A)

Example:
If the probability of rain is 0.3, then the chance of no rain is 0.7.

Combinations and Permutations

These concepts involve counting outcomes, especially when choosing or arranging items.

Permutations (Order Matters)

Formula:
P(n,r)=n!(n−r)!P(n, r) = \frac{n!}{(n – r)!}P(n,r)=(n−r)!n!​

Example:
How many ways to arrange 3 out of 5 patients in a line?
5!(5−3)!=1202=60\frac{5!}{(5 – 3)!} = \frac{120}{2} = 60(5−3)!5!​=2120​=60

Combinations (Order Doesn’t Matter)

Formula:
C(n,r)=n!r!(n−r)!C(n, r) = \frac{n!}{r!(n – r)!}C(n,r)=r!(n−r)!n!​

Example:
How many ways to select 2 medications from 4?
4!2!2!=244=6\frac{4!}{2!2!} = \frac{24}{4} = 62!2!4!​=424​=6

Tip: Use combinations when selecting, permutations when arranging.

Real-Life TEAS-Style Measurement & Data Word Problems

Example 1: Dosage Volume Calculation

A nurse needs to administer 250 mL of IV fluid over 4 hours. How many mL per hour?

2504=62.5\frac{250}{4} = 62.54250​=62.5 mL/hour

Example 2: Statistical Interpretation

A nurse collects patient heart rates: 72, 76, 80, 76, 84.
Find the mean and mode.

Mean = 72+76+80+76+845=388/5=77.6\frac{72+76+80+76+84}{5} = 388/5 = 77.6572+76+80+76+84​=388/5=77.6
Mode = 76
